Browser-to-browser file sharing

By the WispFile team · Updated 24 September 2026

Browser-to-browser file sharing sends files from one web browser directly to another, with nothing installed and nothing uploaded. You open a page, add files and share a link; the other person opens the link and their browser downloads straight from yours. It works across operating systems, because the only thing both sides need is a modern browser.

Key facts

  • No app, no plugin, no account on either side.
  • Works across Windows, macOS, Linux, Android and iOS browsers.
  • Files go browser to browser; the website only introduces the two.
  • Both browsers must stay open until the transfer finishes.

How a browser can send files at all

For years browsers could only talk to servers. WebRTC, now built into every major browser, lets two browsers open a direct, encrypted connection to each other, originally for video calls. A data channel on that connection carries any bytes, including files. The website you use provides the page and a way for the two browsers to exchange connection details; after that, the file does not pass through the site.

The deeper mechanics (signaling, STUN, TURN, flow control) are covered in WebRTC file transfer, explained.

What each browser does on the receiving side

Sending works the same everywhere: the browser reads the files you pick. Receiving differs, because browsers give websites different ways to save files:

  • Chrome and Edge (desktop): the receiver chooses a folder, and files and subfolders are written straight into it as they arrive.
  • Other browsers: files arrive as a normal download. Several files come as one ZIP, built while it downloads, so memory use stays flat.
  • Phones: files go to Downloads. Keep the screen on: mobile browsers pause pages in the background (WispFile holds a screen wake lock while it works).

Status: verified end to end in Chromium-based browsers; Firefox and Safari are going through the test matrix.

Limits worth knowing

  • The sender’s tab must stay open; closing it pauses the transfer.
  • Some networks block direct connections. Free WispFile links are direct only; paid plans add an encrypted relay.
  • Speed is set by the slower connection, usually the sender’s upload.

Share a file browser to browser now

  1. Open wispfile.com.
  2. Drop in files or a folder, or tap Photos on a phone.
  3. Share the link or show the QR code.
  4. Keep the page open until the other side has everything.

Frequently asked questions

Can I send files between browsers without installing anything?

Yes. Modern browsers can connect directly to each other with WebRTC and pass files over that connection. A site like WispFile provides the page and introduces the two browsers; neither side installs an app or creates an account.

Does it work between different browsers, like Chrome and Firefox?

WebRTC is a web standard, so different browsers can connect to each other. So far, WispFile transfers are verified end to end in Chromium-based browsers (Chrome, Edge); Firefox and Safari are in testing.

Can I send to a phone from a computer?

Yes. Create the link on the computer and scan its QR code with the phone, or the other way round. Keep the sending screen on: phones pause pages that go into the background.

Where does the file go on the receiving side?

Chrome and Edge let the receiver pick a folder and write the files straight into it, keeping folder structure. Other browsers save through the normal Downloads, with several files arriving as one ZIP.
